I stablished a portchannel between a Stack of switches 2960X and a pair of 4500 in VSS. This portchannel uses 4 TenGig ethernet optical interfaces (2 in the 2960X stack and 1 on each 4500) using this tranceiver SFP-10G-AOC5M. Due to a better design we require to move one 4500, to another location in the same buiding not far. But for the distance it is necesary to change the transceiver to this one SFP-10G-SR on both ends, one will be place in the remote 4500 and one in the 2960 stack. My question is ¿having a portchannel with 2 different tranceivers in it (SFP-10G-AOC5M and SFP-10G-SR) will have an impact on the operation?, ¿will it even work?. Should I change all the tranceivers to only one type of them  in order for this to work?     Any information will be apreciated   Thanks ... View more

For what i can understand, an ESA Appliance or Cisco CES is not required to be able to send encripted mails if you have an CRES account. If so, how can i purchase only the CRES account?   Regards, ... View more

Hi,   I was looking for a deployment guide regarding Zixgateway with Cisco. I saw many advantages using a Zixgateway over CRES, unfortunatley i havent found any documentation regarding the deployment or how should i send traffic to the zixgateway from the ESA. Does it need to be configured over an outgoing content filter and if so, should I specify the conditions in which the mail will be encripted on the ESA.   Any feedback please.   Thanks. ... View more
